General Competitive Advantages

Unplugged Operation

PRS Reefer Containers, after the Full Thermal Charge, maintain the optimal internal temperature and relative humidity for 25 days*, without any electric power supply or fuel consumption.

Thermal autonomy in ATP conditions after Full Thermal Charge (ATP: Agreement on the International Carriage of Perishable Foodstuffs and on the Special Equipment to be Used for such Carriage)

This allows PRS Reefer Containers to be handled as dry containers at multimodal terminals as ports, truck logistic centers and rail terminals, thus guaranteeing the end-to-end uninterrupted and unplugged cold chain.

81,9% Energy Saving

Saving 81,9%

PRS Reefer Containers are environmental friendly: while the energy consumption of conventional reefers depends on the continuous onboard power generation, that of PRS Reefer Containers is limited to the Pre-Trip Thermal Charge.

During the above-mentioned test, the power consumption of the PRS Reefer Container has been 799 kWh, the one of the conventional reefer has been 4.426 kWh.

Effects of Uniform Temperature Distribution on Quality Preservation

Conventional reefer containers have a cooling compressor on the front wall and an air channel to distribute cold air inside the container, resulting in a non-uniform temperature.

End-to-End Transport Cost Reduction

The PRS Reefer Containers guarantee a major end-to-end transport cost reduction by traveling as a dry unit from the field to its final destination without interruption of the cold chain.

On the opposite, the conventional reefer containers require a continuous power supply and therefore have to be equipped with a clip-on genset to cover the transport from the packinghouse to the loading port. At the port of discharge, the transfer of the load occurs either by unstuffing the load and placing it on a reefer truck or by transferring it on a truck with genset.

Upstream and Downstream Operations - Elimination of Transshipment

Upstream operations are considerably simplified, as some processes for the handling of foodstuff before shipment are not requested with PRS Reefer Containers.

Downstream operations are also simplified by PRS Reefer Containers, allowing Thermopallets and Thermoboxes to be moved, loaded and handled as dry units.

Ship-Rail-Road Intermodal Logistics - Elimination of Human Operations

While the operation of conventional reefer containers requires plugging / unplugging / monitoring and servicing, PRS Reefer Containers are handled as dry containers, and thus saves operating costs as they are directly loaded on a train or truck without genset.

Cost-Saving and Sustainability for Marine Logistics

The low sulfur requirements, as established by the International Maritime Organization (IMO), are significantly affecting the fuel cost for the power supply of conventional reefers. The elimination of onboard power consumption of PRS Reefer Containers results in very significant operating cost reduction, as the average onboard daily energy consumption of a conventional marine chilled reefer container is 184 kW or 7.6 kWh.

Optimized Airfreight Logistics for the Transport of Fresh Foodstuff and Pharmaceutical Products

PRS Airfreight Thermopallets guarantee a five-day unplugged continuity of the cold chain thus avoiding the thermal shocks that occur during truck-depot-airplane-depot-truck transshipments from their origin to their destination. These thermal shocks can severely affect the quality of foodstuff and the effectiveness of vaccines.

Ship-Rail-Road-Air Integrated Logistics

The PRS high quality of preservation and the uninterrupted cold chain also enables marine transport for highly perishable, fresh foodstuff and pharmaceutical products

The planning issue of the supply chain and the emergency supplies are drastically simplified by the long-term storage capability of PRS, which enable the issues of planning supply chain and emergency supplies are drastically simplified by the long-term storage capability of PRS, which enable keeping sufficient stock where the excellent quality of preservation compensates sudden surges and the slow-down of requests.

Emergency airfreight shipments can, anyhow, be provided using PRS Airfreight Thermopallets, which guarantee the uninterrupted high-quality cold chain.

Totally Noise-Free

PRS Reefer Equipment, being with no moving parts, are noise-free: terminals, stations, distribution platforms, truck rest areas and city distribution are therefore not affected by the noise level typical of conventional reefer.
